  • 1 tablespoon lemon zest (zest of 2 lemons)
  • 2 tablespoons poppy seeds
  • 1 teaspoon baking powder
  • 1/8 teaspoon fine sea salt


  1. Preheat oven to 375ºF and grease 9×9 baking dish (or similar size).
  2. Whisk Wet Ingredients: In large bowl whisk together eggs, oil, maple syrup, lemon juice, vanilla extract and milk.
  3. Add Dry Ingredients: Add in rolled oats, lemon zest, poppy seeds, baking powder and salt. Fold in any fruit mix-ins if using.
  4. Bake: Transfer batter to prepared baking dish and bake for 35-40 minutes or, until edges are golden and middle is set. You can serve immediately bowl style, or wait about 20 minutes to serve as squares.
  5. Serve this lemon baked oatmeal with your favorite toppings, a little extra maple syrup or honey and enjoy!


Adding berries: Feel free to add up to 1 cup of berries such as blueberries, raspberries, blackberries, etc. Using fresh berries the bake time will remain the same. If using frozen berries, do not thaw them, but your baking time may increase by a few minutes.

To make vegan: Use 2 flax seed eggs and increase baking powder to 1.5 teaspoons, for the best lift.
